Priest–penitent privilege

The priest–penitent privilege, clergy–penitent privilege, clergy privilege, confessional privilege, pastor–penitent privilege, clergyman–communicant privilege, or ecclesiastical privilege, is a rule of evidence that forbids judicial inquiry into certain communications (spoken or otherwise) between clergy and members of their congregation. This rule recognises certain communication as privileged and not subject to otherwise obligatory disclosure, similar to attorney–client privilege between lawyers and clients.
